If this be bigamy, make the most of it! :-)
William Mays and Eva Kamp married in an Oklahoma Presbyterian church in 1925.
In 1928, they married in a Roman Catholic church in the next county.
The state has records for both. I do know they are the same couple. Unlike many other marriage records I've seen, neither form has anything about whether or not previously married.
I am not sure how to look up Oklahoma's laws and customs at that time. Should I be looking for a divorce or annulment between? Should I assume they went to the next county because the first county would have rejected a second license application?
Should each marriage be treated as a separate family in GEDCOM?
